The Boeing 777, commonly referred to as the Triple Seven, is an American long-range wide-body airliner developed and manufactured by Boeing Commercial Airplanes. It is the world's largest twinjet. The prototype was rolled out in April 1994, and first flew in June. The 777 entered service in June 1995. Longer range variants were launched in 2000, and were first delivered in 2004. It can accommodate a ten–abreast seating layout and has a typical 3-class capacity of 301 to 368 passengers, with a range of 5,240 to 8,555 nautical miles (9,700 to 15,840 km). It is recognizable for its large-diameter turbofan engines, six wheels on each main landing gear, fully circular fuselage cross-section, and a blade-shaped tail cone. It is the first Boeing aircraft with fly-by-wire controls.The 777 Classics is powered by 77,200–98,000 lbf (343–436 kN) General Electric GE90, Pratt & Whitney PW4000, or Rolls-Royce Trent 800 engines. More 777s have been ordered and delivered than any other wide-body airliner; as of December 2022, more than 60 customers had placed orders for 2,141 aircraft of all variants, with 1,701 delivered. The most common and successful variant is the 777-300ER with 838 aircraft ordered and 832 delivered. By March 2018, the 777 had become the most produced Boeing wide-body jet, overtaking the Boeing 747. As of September 2021, the 777 had been involved in 31 aviation accidents and incidents, including 8 hull losses with 541 fatalities, and 3 hijackings.

The 777-200LR ("LR" for Long Range), entered service in 2006 as one of the longest-range commercial airliners. Boeing nicknamed it Worldliner as it can connect almost any two airports in the world. It holds the world record for the longest nonstop flight by a commercial airliner. It has a maximum design range of 8,555 nautical miles (15,844 km) as of 2017. The -200LR was intended for ultra long-haul routes such as Los Angeles to Singapore. Developed alongside the -300ER, the -200LR features are three optional auxiliary fuel tanks in the rear cargo hold. Other new features include extended raked wingtips, redesigned main landing gear, and additional structural strengthening. As with the -300ER and 777F, the -200LR is equipped with wingtip extensions of 12.8 ft (3.90 m). The -200LR is powered by GE90-110B1 or GE90-115B turbofans. The first -200LR was delivered to Pakistan International Airlines on February 26, 2006. Twelve different -200LR customers took delivery of 61 aircraft.

777F (777-200LRF)
The 777F is a cargo version of the twinjet, and shares features with the -200LR; these include its airframe, engines, and fuel capacity. With a maximum payload of 228,700 lb (103,700 kg), it has a maximum range of 9,750 nmi (18,057 km) or 4,970 nmi (9,200 km) at its max structural payload. The first 777F was delivered to Air France on February 19, 2009. As of April 2021, 247 freighters have been ordered by 25 different customers with 45 unfilled orders. Operators had 202 of the 777Freighters in service as of 2018.



777-300
The 777-300 was launched at the Paris Air Show on June 26, 1995, its major assembly started in March 1997, rolled-out on September 8 and made its first flight on October 16. The 777 was designed to be stretched by 20%: 60 extra seats to almost 370 in 3-class, 75 more to 451 in two classes, or up to 550 in all-economy. The 33 ft (10.1 m) stretch is done with 17 ft (5.3 m) in ten frames forward and 16 ft (4.8 m) in nine frames aft for a 242 ft (73.8 m) length. It uses 84,000–98,000 lbf (374–436 kN) engines. Boeing wanted to deliver 170 -300s by 2006 and to produce 28 per year by 2002. With 90,000 lbf (400 kN) engines, it has a range of 6,005 nautical miles (11,121 km) with 368 passengers in three-class.

777-300ER
A 777-300ER is the best-selling variant The 777-300ER ("ER" for Extended Range) is the version of the -300. It increased fuel capacity permits a maximum range of 7,370 nautical miles (13,650 km) with 396 passengers in a two-class seating arrangement. The 777-300ER features raked and extended wingtips, a strengthened fuselage and wings and a modified main landing gear. It is powered by the GE90-115B turbofan, the world's most powerful jet engine with a maximum thrust of 115,300 lbf (513 kN). Following flight testing, aerodynamic refinements have reduced fuel burn by an additional 1.4%. The first 777-300ER was delivered to Air France on April 29, 2004. The -300ER is the best-selling 777 variant, having surpassed the -200ER in orders in 2010 and deliveries in 2013. As of 2018, 784 Boeing 777-300ERs were in service.

777-300ERSF (Special Freighter )
In July 2018, Boeing was studying a 777-300ER freighter conversion. New-build 777-300ER may maintain the delivery rate at five per month, to bridge the production gap until the 777X is delivered. Within the 811 777-300ERs delivered and 33 to be delivered by October 2019. In October 2019, Boeing and Israeli Aerospace Industries (IAI) launched the 777-300ERSF passenger to freighter conversion program. In June 2020, IAI received the first 777-300ER to be converted. The converted aircraft has a maximum payload of 224,000 lb (101.6 t), a range of 4,500 nmi (8,300 km). It has a cargo volume capacity of 28,900 cu ft (819 m3), 5,800 cb ft (164 m³) greater than the 777F (or 25% more).



Boeing 777X
The 777X is to feature new GE9X engines and new composite wings with folding wingtips. It was launched in November 2013 with two variants: the 777-8 and the 777-9. The 777-8 provides seating for 384 passengers and has a range of 8,730 nmi (16,170 km) while the 777-9 has seating for 426 passengers and a range of over 7,285 nmi (13,500 km). The 777-9 first flew on January 25, 2020, with deliveries initially forecast for 2022 and later delayed to 2023. A longer 777-10X, 777X Freighter, and 777X BBJ variants have also been proposed.
